SUMMARY
Fuertes-Olivera and Tarp's Theory and Practice of Specialised Online Dictionaries is a long-awaited volume, offering a systematic description of the tenets of function theory. The authors present this theoretical framework both as a guideline in order to accomplish different lexicographical tasks (i.e. from compiling dictionaries to assessing the lexicographical suitability of other theoretical models), and as a valuable methodological tool which can be used to detect the users' needs. The 'Functional approach' is thus considered to be an alternative method to the research on users' behaviour. However, not only the new ideas and the terminology used within this field of lexicographical research deserve attention, but also some issues related to the concept of specialised lexicography, which are briefly outlined by Fuertes-Olivera and Tarp in the book. Their definition of this sub-discipline stimulates further reflections on the epistemic status of the two branches of lexicography (general and specialised) as well as on the related concepts of general and cultural knowledge.
